Analog Devices Inc./Maxim Integrated DG413DY+

Overview

DG413DY+ from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, designed for bidirectional signal routing in precision analog systems. It delivers 35Ω max on-resistance, <5nA off-leakage at +85°C, and 150ns max tON - enabling high-fidelity signal switching in battery-powered test equipment and military radios.

For engineers reviewing the DG413DY+ datasheet, DG413DY+ pinout, DG413DY+ application, or DG413DY+ equivalent, key selection criteria include guaranteed RDS(ON) matching (≤3Ω), rail-to-rail analog signal handling (±15V), TTL/CMOS logic compatibility, and ESD tolerance ≥2000V per Method 3015.7.

Technical Context

The DG413DY+ implements four independent CMOS transmission gates fabricated in a 44V silicon-gate process, supporting both single-supply (+10V to +30V) and bipolar-supply (±4.5V to ±20V) operation. Its dual supply architecture enables true rail-to-rail analog signal swing while maintaining low charge injection (≤10pC) and flat on-resistance (Δ4Ω max) across the full input range.

Each channel features break-before-make timing (25ns delay for DG413 configuration), low dynamic power consumption (35µW max), and logic-level translation via dedicated VL pin - allowing interface with 3.3V or 5V controllers without level-shifting circuitry.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog signal range supported by DG413DY+?

DG413DY+ supports rail-to-rail analog signals from V− to V+, enabling ±15V operation with ±15V supplies or 0V to +12V with +12V single supply. The absolute maximum analog voltage is limited by the supply rails - signals exceeding V+ or falling below V− are clamped by internal diodes, so proper supply sequencing is essential to avoid damage. DG413DY+ maintains specified performance across the full range.

Does DG413DY+ require external pull-up resistors on its IN pins?

No, DG413DY+ does not require external pull-up resistors on IN1–IN4. Its TTL/CMOS-compatible inputs have defined thresholds (VINH = 2.4V, VINL = 0.8V) and low input current (±1µA max), allowing direct connection to microcontroller GPIOs or FPGA outputs. The VL pin sets logic reference, so tying VL to 5V ensures robust noise margin without external biasing components.

Can DG413DY+ operate with unbalanced supplies like +24V and −5V?

Yes, DG413DY+ supports unbalanced supplies such as +24V and −5V, provided the total voltage difference (V+ − V−) does not exceed 44V and each rail stays within absolute maximum ratings. This capability allows flexible integration into legacy systems with asymmetric power domains, though on-resistance and leakage will reflect the actual applied voltages - verified in the Electrical Characteristics tables for dual-supply conditions.

How is the two-NC/two-NO configuration implemented in DG413DY+?

In DG413DY+, pins IN1 and IN4 control the two normally closed (NC) switches (S1↔D1 and S4↔D4), while IN2 and IN3 control the two normally open (NO) switches (S2↔D2 and S3↔D3). When logic low is applied, NC channels conduct and NO channels disconnect; logic high reverses the state. This arrangement enables simultaneous path enablement and termination - for example, connecting one sensor while grounding another unused input.

Is DG413DY+ pin-compatible with older DG413 variants like DG413DJ or DG413CJ?

Yes, DG413DY+ shares identical pinout, footprint, and electrical behavior with all industry-standard DG413 variants including DG413DJ and DG413CJ - it is a drop-in upgrade with improved R_DS(ON) matching, lower leakage, and enhanced ESD tolerance. No PCB changes are required when replacing legacy DG413 parts with DG413DY+, and existing firmware or logic drive levels remain fully compatible.
